{{I have code [here|[https://stackoverflow.com/questions/49440766/trouble-getting-spark-aggregators-to-work],] where I am trying to use an Aggregator with both the `select` and `agg` functions. I cannot seem to get this to work in Spark 2.3.0. [Here|https://docs.cloud.databricks.com/docs/spark/1.6/examples/Dataset%20Aggregator.html] is a blog post that appears to be using this functionality in Spark 1.6, but It appears to no longer work. }} -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
